Congenital Cytomegalovirus (CMV)
Cytomegalovirus (sy toe MEG a low vy rus), or CMV, is a common cold-like virus that is harmless to most people. Most people catch CMV during their lifetime. If CMV passes through the placenta to a growing baby, it can cause birth defects such as hearing loss and developmental delays. There are steps women can take to lower their risk of CMV.
-
Cytomegalovirus (CMV) is common
- CMV is a common, usually harmless, lifelong virus and transmitted from person to person through direct contact with body fluids (urine, saliva, blood, breast milk, and semen).
- CMV can cause cold-like symptoms, such as a sore throat, fever and fatigue, but most often does not cause any symptoms in healthy people.
- Up to 70% of children under 3 years old will catch CMV at daycare or school and remain contagious for several months even though they may not have any symptoms.
- If a pregnant person catches CMV and it is passed to the growing baby, it is called congenital CMV.
- People can catch different strains of CMV. There is no such thing as being immune to CMV.
-
Congenital CMV can cause long term disabilities
- One in every 150 babies in the US are born with congenital CMV.
- One in five babies born with congenital CMV will have long-term disabilities and health problems.
- Congenital CMV can cause hearing loss, vision loss, cerebral palsy, seizures, learning and cognitive problems.

Reduce your risk of CMV
The best way to protect your baby from congenital CMV is to protect yourself.

Avoid contact with saliva and urine of young children. You can do this by:
- Washing your hands often with soap and water for 15-20 seconds, especially after:
- Changing diapers
- Feeding a young child
- Wiping a young child’s nose or mouth
- Handling children’s toys
- Do not share food, drinks, eating utensils, or a toothbrush with a child.
- Do not put a child’s pacifier in your mouth.
- Avoid contact with a child’s saliva when kissing or snuggling.
- Clean toys, countertops, and other surfaces that come into contact with children’s urine or saliva.
- Children should be told not to share their cups and utensils.
- Pregnant women who work with young children, such as daycare, nannies, healthcare works or therapy providers, should take extra steps to prevent infection such as wearing gloves when changing diapers.

Testing and Diagnosis
- Healthcare providers can order tests to identify CMV infection. Testing for congenital CMV infection in babies is different than testing for CMV in adults.
- Congenital CMV testing for a baby is simple and painless. It is done using either a urine or saliva sample.
- This testing must be done before the baby is 21 days old to confirm if the baby has congenital CMV.
- Ask your healthcare provider if your baby should be tested for congenital CMV. Get testing as soon as you are told it is needed.
- Providers can read more about Laboratory Testing for CMV and Congenital CMV from the U.S Centers for Disease Control and Prevention (CDC).
